Abstract

This paper deals with the electrostatic charging of material webs in production machines. Measurements were made with a special measurement setup inside a gravure printing press and the results were analyzed and interpreted. In order to gather as much information as possible, the electric field strength of a free-spanning web was monitored at different positions inside the machine and under different production conditions. The measurement results confirmed theoretical principles and practical experience, such as the fact that the type of material, printing inks, coatings, machine speed, web tension, printing process and corona pretreatment have a significant effect on the level and polarity of the electrostatic charging. During the series of experiments, peak field strengths of up to 300 kV/m resulting from the charge on the web were measured and changes in the sign were detected within a very short period of time.

凹版印刷机材料卷筒的静电充电
本文论述了生产设备中材料卷筒纸的静电充电问题。在凹版印刷机内使用特殊的测量装置进行了测量,并对结果进行了分析和解释。为了收集尽可能多的信息,在机器内部的不同位置和不同的生产条件下,对自由伸展的卷筒纸的电场强度进行了监测。测量结果证实了理论原则和实践经验,如材料类型、印刷油墨、涂层、机器速度、卷筒纸张力、印刷工艺和电晕预处理对静电荷的水平和极性有显著影响。在一系列实验中,测量到卷筒纸上的电荷产生的峰值场强高达 300 kV/m,并在很短的时间内检测到符号的变化。
